The water oxidation (WO) activity of a chlorinated cobalt tetraphenylporphyrin (CoClPS), possessing Cl atoms on the 2,6-positions of the aryl groups, shows higher resistance to attack by singlet oxygen, in situ generated during photochemical WO using Ru(bpy)3(2+) and S2O8(2-) with the turnover frequency (TOF) and turnover number (TON) reaching 1.7 s(-1) and 836, respectively.

The photosensitivity of metal carbonyls has been known almost as long as the class of coordination compounds itself. Among no other group of inorganic compounds may one find so many light-sensitive materials. Hence photochemical reactions of metal carbonyls have found wide applications for synthetic purposes. However, whereas much research has been done to understand the thermal reactions," the...

Two novel peroxo titanium complexes, Li(2)(NH(4))(4)[Ti(2)(O(2))(2)(cit)(Hcit)](2).5H(2)O and Zn(NH(4))(4)[Ti(4)(O(2))(4)(Hcit)(2)(cit)(2)].12H(2)O (cit = citrate), show encouraging results in the photochemical oxidation of 2-propanol.

background: there are many varieties of compounds in chemical and petrochemical wastewater. one of the important members of the chlorophenols (cps) family is ρ-chlorophenol. this pollutant is introduced into the environment through various human activities such as waste incineration, uncontrolled use of wood preservatives, pesticides, fungicides and herbicides, as well as via bleaching the pulp...
